HTC One X & One S Go On Sale in the U.K. Today

The first two smartphones from HTC's new One series have gone on sale in the U.K. today. Both the One X and the One S are available from a number of carriers, including O2, Orange, T-Mobile, Three and Vodafone.

Both handsets are running Android 4.0 Ice Cream Sandwich, complimented by HTC's own Sense 4.0 user interface. The One X is the flagship model, boasting an NVIDIA Tegra 3 quad-core processor at 1.5GHz, a 4.7-inch 1280×720 display, an 8-megapixel camera, and 32GB of internal storage. But of course, all that means it'll cost you a little bit more.

The cheaper One S offers a 1.5GHz dual-core processor, a 4.3-inch 540×960 display, an 8-megapixel camera, and 16GB of internal storage.

Prices start at around £36 (approx. $57) per month on a two-year contract, and according to The Verge, Three is offering the best deal with its popular One Plan. However, O2's new 'On & On' tariff, which the company describes as its best yet, is pretty close.

If you'd prefer to ditch the commitment — or you already have one — and you'd like to but the One X or the One S SIM-free, you can pick them up on Amazon for £489.99 (approx. $780) and £414.99 (approx. $660) respectively.
